Abstract

The invention discloses a signal processing system for a carbon baking kiln gas temperature alarm device. The system mainly comprises a processing chip U, a triode VT2, a polarity capacitor C7, a resistor R8, a diode D3, a signal reception low pass filtering circuit which is separately connected with a base electrode of the triode VT2 and a VC base pin of the processing chip U, and a frequency error correction circuit connected with the processing chip U. The system is advantaged in that useless signals of signals can be inhibited or eliminated, phases and frequency errors of output signals can be adjusted to make the output signal be stable, so signal processing accuracy is improved, and the temperature alarm device is guaranteed to accurately alarm when carbon baking kiln gas temperature is overhigh.

Description

technical field [0001] The invention relates to a signal processing system, in particular to a signal processing system for a carbon roasting furnace flue gas temperature alarm device. Background technique [0002] Carbon roasting furnaces usually use petroleum coke and pitch as raw materials. Under high temperature conditions, the roasting workshop completes the roasting of vibration-shaped raw carbon blocks into qualified cooked carbon blocks. The temperature of raw carbon block is 200-1200°C during the roasting process, and a large amount of roasting flue gas is released during this process. The main components of the roasting furnace flue gas are asphalt fume, tar and various combustible dust, and the flue gas outlet temperature is as high as 900°C. At high temperature, these flue gases must be discharged from the flue in time, otherwise it is easy to overheat and burn, and even cause an explosion. At present, in order to prevent accidents caused by excessive temperatur...
